Not. onlywere these improved screens not used for protecting windows or forbuilding up unusually rigid at the corners of the frames, but partitions to fenceoff and protect' stock rooms the applicationof the cloth was extremely slow 5 and thelike although, of course, such framed and laborious. Furthermore, the cloth extended 5 screens have manyother uses, such as in outdoor across thecenter of the frame so that bolts for electric signsfor sup-porting the illuminated letjoining the sections together were not practicable;

With screen guards as heretofore constructed composed of both a metal channel and a metal the frames were commonly made of heavy wire or angle, both structural forms having exceptional 4 round bars bent into rectangular form and the rigidity. Furthermore, since the ends of the cloth was applied to these frames by bending the 'frame bars are mitered and welded together the edges of the cloth around the frame bars. With frame is exceptionally rigid at its corners, parsuch a construction not only was the frame far ticularly in view of its cross sectional shape which from rigid but the cloth could not be rigidly seprovides an adequate welding surface both diagcured to this frame and frequently presented proonally of the screen bars and also transversely 4 jections which were liable to catch clothing or thereof. Also since each screen wire is individcause injury. In an improved form of such ually spot welded at its opposite ends to the frame screen guards the frame was built up of outwardly the cloth is securely united to the frame and canfading c an s jo ne a their s y p v d g not be loosened under any usual conditions.

Furthermore it will be seen that 55 the greater part of the webs l are exposed so that bolts, such as the bolt H, can be readily passed through these webs in uniting several frames to forma partition. Thus, in Fig. 4, two screen sections are joined together with their flanges 9 and I in edge to edge relation and the webs 8 connected by the bolt I4. Screen sections so joined together provide a rigid partition, the bars ofwhich are of smoothexternal formsd as to be readily kept free of dirt and the partition presents no unsightly protuberances, the only exposed parts, other than the regular flat faces of the bars, being the heads and nuts of the bolts ll.

From the foregoing it will be apparent that the present invention provides a screen frame which is exceptionally strong and rigid in construe tion both because of the particular cross sectional shape of the bars and also because of the mitered and welded joints connecting the ends of the bars. Further, the screen cloth is firmly and rigidly united to the frame by the extremely simple spot welding process so that the frame and cloth cannot become sleazy or warped. Also it will be observed that the screen sections peculiarly lend themselves to the construction of neat and rigid partitions by the simple expedient of belting them together as illustrated in Fig. 4. v

I claim as my inventlon:--

1. An article of the characterdescribed, com prising a plurality of metal angle bars joined at their ends to provide a frame, one set of the legs of said angle bars being joined end to end and being disposed in the same plane and the other set extending laterally in the same direction from said first set and a piece of relatively heavy gage wire cloth the strands of which are arranged in a common plane and set into said'frame and having their ends welded at one side to the inner faces of said first set of legs.

2. An article of the character described, corn prising a plurality of metal bars joined at their ends to provide a frarre, each of said bars being h-shaped in cross section and having a central web disposed at right angles to the general plane of the frame, a flange projecting inwardly from one edge of said web and forming, in effect, an inwardly facing angle bar and a pair of flanges projecting outwardly from the edges of said web in the opposite direction from said flrst flange and forming, in effect, an outwardly facing channel, and a piece of relatively heavy gage wire cloth the strands of which are arranged in a common plane and secured at their ends to said frame.

An article of the character described, comprising a plurality of metal bars joined at their ends to provide a frame, each of said bars being h-shaped in cross section and having a central web disposed at right angles to the general plane of the frame, a flange projecting inwardly from one edge of said web and forming, in effect, an inwardly facing angle bar and a pair of flanges projecting outwardly from the edges of said web in the opposite direction from said flrst flange and forming, in effect, an outwardly facing channel, and a piece of relatively heavy gage wire cloth the strands of which are arranged in a common plane and set into said frame and having their ends welded at one side to the inner faces of said inwardly extending flanges.

An article of the character described, comprising a plurality of metal bars of generally h-shaped form in cross section, the ends of said bars being mitered and butt welded together to form a frame, said bars each comprising a central web disposed at right angles to the general plane of the frame, a flange projecting inwardly from one edge of said web and forming, in effect, an inwardly facing angle bar and a pair of flanges projecting outwardly from the edges of said web in the opposite direction from said first flange and forming, in effect, an outwardly facing channel and a piece of relatively heavy gage wire cloth the strands of which are arranged in a common plane and set into said frame and having their ends welded at one side to the inner faces of said inwardly extending flanges.
